The central element in the lower part of the shield is the Celtic cross. The green cross stands for Ireland. A specific Montreal reference is provided via the narrow red cross set in the centre of the larger cross. This alludes to the cross on the unofficial arms and flag of the city. The regal gold background recalls Christ the King who resides in the House of the Lord. The Basilica itself is referred to in the upper left hand quadrant of the shield through the representation of the central tower and flanking towers from the south facade. Across the top, on the blue chief, is a harp underscoring that the parish was founded to serve Irish Catholics. The crossed keys, which are the Papal insignia, signify that the parish church was made a minor basilica by Pope John Paul II. The maple leaf charged with a fleur-de-lis further represents the location of the parish within Canada and Quebec.
